All problems are solvable. There is no earthly reason why every single problem besetting sub Sahara Africa, or anywhere else on this planet, cannot be solved. Each of us has talents or skills that can be directly applied to a specific problem. If one reads the book, Guns, Germs and Steel, one can see how geography determines destiny but that the geography, and therefore, the destiny, can be modified by human activity. If overgrazing causes desertification, reforestation can revivify a region and reopen it to agriculture. Look at the talents we possess. I, myself, understand how transportation is essential to moving goods to market, and thereby raising the standard of living. So if I could do anything to improve the lives of people it would be in using this skill to create a transportation infrastructure that would enable the free exchange of goods at the lowest possible cost. When people have the chance to trade their goods for items they want, but cannot themselves produce, they create surpluses that they exchange for those goods, improving their conditions and that of their trading partners. I would like to help establish means of transportation to move those goods. Perhaps that means nothing more than an all weather paved road from A to B or maybe a narrow guage railroad from hinterland to port facility, rather than an international airport. If I could do those things, use that talent, I would be mighty happy to do so.
